Thread: Trolling motor 12 or 24 Volt

I own a BT 175 with the stock 12v 43# Tm and fish a couple electric only lakes, on windy days 10mph and windier I would drain the battery down. Decided to upgrade Tm to a 24v 80# MG XI5 and after much reading and price comparing going to a 24 v system made perfect scents. I added a battery and went to a 3 bank charger but later realized My 50 merc would charge the cranking battery so a 2 bank charger would of been enough, I added a 50 amp fuse and used the stock guage wire and havent had any issues.
I would check to see if your gas motor re charges your cranking battery, if so You would need a 2 bank charger for a 24v TM or check to see if you have a single or a 2 bank charger on the boat now that would let you know if the motor charges the cranking battery.
PS. I love the new Tm never ever have come close to running down the batteries.

Go 24v..IMO there is no such thing as too big, when it comes to elec trolling motors
